Explaining the Patterns of Effective Factors on Supply Chain in the Offshore Sector of Oil and Gas Industry

Today, due to the ever-increasing competition between organizations and uncertain environments that have been created by many changes in customer needs, using an efficient supply chain can be considered as a competitive advantage for any organization. In this regard, one solution is lean approach. Lean approach helps to eliminate waste in the supply chain. On the other hand, based on the state of Iran and the abundance of oil and gas resources, the implementation of lean approach in the supply chain of the organizations operating in this field is very important.In order to conduct this study, that has been carried out in one of the largest companies operating in the offshore sector and the objective is to achieve an supply chain. First, by reviewing the literature, eight key factors that lead to the lean of the supply chain were identified and using the tool of the questionnaire and distributing between statistical sample and statistical analysis were effective. Then, using an interpretive structural modeling approach, the research model was developed. In the next step, the model was validated in quantitative and statistical analyzes as well as qualitative and based on it, the factors: financing, leadership and management, and communication with the supplier were identified as the most influential and minimizing the delivery time and flexibility were identified as the most impressive factor. Finally, some suggestions were made to achieve lean procurement process in the offshore sector of the oil and gas industry.
